Abstract

A carbon dioxide (CO 2 ) capture system and method for removing CO 2 from an inlet gas including a first fluid stream inlet providing for the flow of a first fluid stream, such as an inlet gas containing CO 2 , and a second fluid stream inlet providing for the flow of a second fluid stream, such as steam, an outlet providing for the flow of a CO 2 depleted stream from the CO 2 capture system, an outlet providing for the flow of a CO 2 stream from the CO 2 capture system and a concentrator in fluid communication with the first fluid stream. The system further including a first contactor and a second contactor. Each of the first contactor and the second contactor defining therein a first fluidically-isolated, sorbent-integrated, fluid domain for flow of the first fluid stream and CO 2 adsorption and a second fluidically-isolated fluid domain for flow of the second fluid stream to assist in desorption.

a plurality of fluidically-isolated, thermally-connected, parallel fluid domains disposed in the first contactor body between the first end and the second end orthogonal to the fluid flow path, wherein the plurality of fluidically-isolated, thermally-connected, parallel fluid domains include:
a plurality of sorbent-integrated fluid channels, each sorbent-integrated fluid channel defining a flow path for the fluid stream passing from the first end to the second end of the first contactor body; and
a plurality of heat transfer fluid channels thermally connected to the plurality of sorbent-integrated fluid channels in an alternating arrangement, each heat transfer fluid channel defining a flow path for a heat transfer fluid stream that flows orthogonally to the fluid flow path between the first end and the second end of the first contactor body; and
a second contactor to operate in conjunction with the first contactor, the second contactor including:
a second contactor body having a first end with a fluid stream inlet to receive the fluid stream, a second end with a fluid stream outlet to release the fluid stream, and a fluid flow path extending between the first end and the second end that directs the fluid stream received by the fluid stream inlet to the fluid stream outlet for release therefrom; and
a plurality of fluidically-isolated, thermally-connected, parallel fluid domains disposed in the second contactor body between the first end and the second end orthogonal to the fluid flow path, wherein the plurality of fluidically-isolated, thermally-connected, parallel fluid domains include:
a plurality of sorbent-integrated fluid channels, each sorbent-integrated fluid channel defining a flow path for the fluid stream passing from the first end to the second end of the second contactor body; and
a plurality of heat transfer fluid channels thermally connected to the plurality of sorbent-integrated fluid channels in an alternating arrangement, each heat transfer fluid channel defining a flow path for the heat transfer fluid stream that flows orthogonally to the fluid flow path between the first end and the second end of the second contactor body.
